HARROVV-TOOTi-iv AND HOLDER.

SPECIFICATION forming part of Letters Patent No. 328,992,dated October 27, 1885.

Application filed. February 4, 1885.

To all whom it may concern.-

Be it known that I, GEORGE E. WILOOX, a citizen of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa, have invented a new and useful I1nprovement in Harrow-Teeth and Holders, of which the following is a specication, reference being had to the accompanying drawings.

My invention relates to a`harrow-tooth and holder for reversible harrows; and it has for its object to provide devices of this character which shall be cheap and simple in their construction, effective in operation, strong and durable, and easily put together or taken apart.

With these ends iu view the invention consists in the improved construction and com-V binations of parts, hereinafter fully described, and pointed out in the claims.

In the drawings, Figure lis aside elevation of a barrow-tooth and holder and the means of attaching the same to the barrow-frame. Fig. 2 is a section showing the harrow-tooth held rigid in a vertical position, and showing in dotted lines the positionit occupies when reversed. Fig. 3 is a detail view of the hold-i er-plates, and Fig. 4 is a detail View of the harrow-tooth.

In the accompanying drawings, in which like letters of reference indicate corresponding parts in all the figures, A represents two parallel plates the ends of which are adapted to be connected to the harrow-frame. (Not shown.) In thedrawings only one of the plates is shown. The other one is of the same construction, and is arranged similar to the one shown and described, but located on the opposite side of the tooth. Upon the plates A is adapted to be arranged a holder, B, whichV consists of an upper and a lower section, C C. Extending downwardly from the upper section, near each end thereof, is a lug, a c', and between said lugs the said section is provided with a semicircular recess to form a seat, b said section is also provided on its upper side, nea-r one end thereof, with an integral hook, A, which is adapted to receive one of the series of diagonal bracing-bars b of the harrowframe. The lower section, C', is provided near each end with an upwardly-extending ASerial No. 154,904. (No model.)

lng, c, and is provided near the rear lug with an elongated slot, d. Near the forward lug the plate is recessed or cut away to form a seat, e. I

D represents a rigid straight harrow-tooth, which is pointed` at its lower end, as usual. The upper end of this tooth is turned forwardly and downwardly, upon itself' to form an eye or loop, e. The upper and lower sections are provided midway between their ends, and upon each side thereof, the lower with upwardly-extending shoulders and the upper with downwardly-extending shoulders f. Said plates are also provided at their ends with holes or openings for the passage of bolts for securing them together.

My improved holder and tooth are applied as follows: The tooth is inserted through the slot or opening of the lower section, from the upper side thereof, its head resting in the seat e with its lower side. The said lower section, carrying the tooth, is adjusted upon the parallel bars or plates A, ou the under side thereof, said bars fitting between the shoulders and lugs. The upper section is then placed upon the upper sides of the bars, the said upper sides of the bars fitting between the lugs and shoulders on said upper section. The bolts g are then passed through the registering-openings of the sections and secured in place by nuts, as shown. Then the harrow is moved forward, the tooth bears against the rear end of the slot in the lower section with its rear side, 'its front side bearing in the seat e. rIhe said tooth is thus held rigidly in a vertical position. When the harrow is reversed, the tooth is allowed to play to the forward end of the slot of the lower section, the body portion of the tooth bearing against the front end of said slot, while its head bears against the rear lugs of the sections.

It will be seen that by my improvement the 'barrow-tooth may be readily and quickly adj Listed in position upon the harrowd'rame, that the improvements are cheap, simple, thoroughly effective in their operation, and .strong and durable.

Having fully describedI my invention, what I claim as new, and desire to secure by Letters Patent, isn IOO l. lThe barrow-tooth headed at its upper l having a head at its upper end, substantially 2o end, in combination with a holder consisting 0f two sections each of which is formed with one-half of the seat for the head of the tooth7 so that when both sections are fitted together a complete seat is formed for said head, as set forth.

2. The combination', with a holder consisting of an upper and a lower section, the upper section having a semicircular seat and the lower section having an elongated slot, and a seat, e, of a barrow-tooth having a head at its upper end, substantially as set forth.

3. The combina-tion, with a holder consisting of an upper and a lower section, the upper section having a semicircular seat and downwardly-extending lugs and the lower section having an elongated slot, a seat, e, and

upwardly-extending lugs, of a barrow-tooth as set forth.

4. The combination, with the barrow-frame, of a holder consisting of an upper and a lower section, the upper section having a semicircular seat and downwardly-extending lugs and ears and the lower section having an elongated slot, a seat, e, and upwardly-extending lugs and ears, and a barrow-tooth having a head at its upper end, said sections being adapted to be secured together by bolts, and arranged substantially as shown and described.

In testimony thatI claim the foregoing as my own Ihave hereto affixed my signature in presence of two witnesses.
